Support for binary QR codes

[ferm10n]

Exposes metadata from zxing that includes the byteSegments. This would close #734

From there, you could join all the byte segments like this:

const byteSegments = qrcodeResult.result.metadata?.get(ResultMetadataType.BYTE_SEGMENTS);
if (byteSegments) {
  const totalLength = byteSegments.reduce((prev, curr) => prev + curr.length, 0);
  const concatBytes = new Uint8Array(totalLength);
  let offset = 0;
  for (const byteSegment of byteSegments) {
    concatBytes.set(byteSegment, offset);
    offset += byteSegment.length;
  }
  return new TextDecoder().decode(concatBytes);
}
